LEWIS WILLIAMS, OF JOHN STOWN, PENNSYLVANIA.

SPIKE-GROOVING MACHINE.

SPECIFICATION forming part of Letters Patent No. 685,417, dated October29, 1901.

Application iiled January '7, 1901.4 Serial No. 42,298. (No model.)

T0 all whom it may concern:

Be itknown that I, Lnws WILLAMS, a citizen of the United States,residing at Johnstown, in the county of Cambria and State ofPennsylvania, have invented certain new and useful Improvements inSpike-Grooving Machines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to new and useful improvements in spikemachinery, and more particularly to mechanism for grooving the sides ofsaid spike.

My invention may be used as an independent machine', as shown in thedrawings, wherein a single operation is performed upon a spike, andwhich consists in grooving two sides thereof, as will be later referredto, or it may be used in connection with au automatic machine, as shownin my former patent, No. 600,052, and dated March 1, 1898, wherein mypresent construction would perform one of a series of operations, aswill be apparent.

It is the object of my invention to improve the efficiency of mechanismfor the purpose specified and to produce a machine which is in every Waypracticable andl reliable and whereby a uniform inward pressure isapplied to the spike and tensile strain is avoided.

With the above objects in view my invention resides and consists in thenovel construction and combination of parts shown in the accompanyingthree sheets of drawings, forming a part of this specification, uponwhich similar letters of reference denote like or corresponding partsthroughout the several gures, and of which-- Figure l shows a plan Viewof my novel spike grooving mechanism, together with connections foroperating the same. Fig. 2 is an enlarged front View of said groovingmechanism, the operating-jaws being in an open position. Fig. 3 is asectional plan view on line 3 3 of Fig. 2, the jaws being in a forwardandclosed position. Fig. 4 is a similar sectional plan view, the jawsbeing in an open and rearward position, corresponding with those of Fig.2.V Fig. 5 is'a central vertical longitudinal section on line 5 5 ofFig. 2, the position of parts agreeing with Fig. 4. Fig.

2jaws in the act of operating upon a spike. Fig. 8 is a similar sideview of said jaws but in the act of completing a spike. Fig. 9

vshows side views of a spike-blank before and after being operated uponwith my machine. Referring to the characters of reference marked uponthe drawings, A indicates a base,

my improved mechanism is mounted.

B indicates a top section whose internal arrangement is similar to thatof the lower section and is secured thereto by suitable bolts C, asshown. The forward end of the casing formed by these two sections isopen, as will The opposite end is provided with a plate D, which is alsosecured in position by means of screw-l bolts, as shown, and isAprovided with four openings E, through which links operate, as willlater be more fully described. The construction of the mechanism withinthe case is such as to require a sliding reciprocating movement, whichmay be derived from any suitable sourceas, for instance, from a slidablerod F, mounted in ways G G and provided with a yoke connection H to asuitable crank I of a rotary shaft, it thus being apparent that with arotarymovement of the shaft the rod will be reciprocated to and frowithin its bearings, and by connections, as' shown,

horizontally-disposed levers K K, each haveA ing a link connection Lwith the radial arms M M of the slide-rod F and by means of which saidlevers are thrown to and fro upontheir pivotal points. These levers Kare alsoeach provided with link connections N N to the outer ends ofgroovingjaws O O, both of which are provided with hubs lo and arehorizontally mounted in slidable bearings P I upon each side. Thesebearings slide upon movable ways Q Q, the operative surface of Vwhich isat all times horizontal. The backs R of these ways are inclined, asshown in the drawings, and slide upon a corresponding inclined surfaceof the casing and are provided with a small rib S to engage acorresponding groove 'forming the lower half of a casing in which Y uponthe inner wall of the casings, which groove serves to guide thewedge-shaped way when the latter is pushed forward or backward,andthereby crowding the operative surface thereof Vto or from the center ofthe tool, as the case may be. Between the levers K and the slidablebearings P is provided a direct connection in the form of links T, bymeans of which said bearings are moved to and fro upon the ways. Byreason of the foregoing construction it will be seen that the assemblageof links, levers, bearings, die., operate to and fro by the connectionsL with the driving medium and that the only lined bearings are the twobetween the levers K K and the projection J.

As before stated, the wedge-shaped ways Q, are movable upon an inclinedplane in a manner to open and close the operating-jaws O, and as apreferred means for manipulating said jaws I provide an orifice U ineach of said ways, into which a pin V of the lever K operates. Said' pinprojects from cach side of said lever and loosely fits into said orificeU of the ways upon each side and serves only to engage the ends thereofwhen the lever is in its extreme forward or backward positions, therebymoving the ways slightly after the jaws have been rocked. The purpose ofthis construction, as will be obvious, is to open and close the jawswhen in their extreme backward and forward positions, respectively. Theopening movement releases the engagement of the spike, while the closinggrasps the same. The jaws O perform the grooviug operation by means of acentral rib O upon the semicircular face thereof and by reason of theengagement ofthe outer end of said rib with the upper sides of thespike-blank, as will be apparent from an inspection of Figs. 3, 7, and8, which illustrate the rolling movement of said jaws upon the blank.The head of the blank will be lixed in any suitable clamp (not shown) ina manner to project outward for engagement by the jaws above mentioned.

In addition to the above pair of groovingjaws and mechanism foroperating the same I provide a similar set of mechanism for operatingthe top and bottom jaws, which work in conjunction with saidgrooving-jaws and form the fiat side of the spike, which mechanismconsists as follows:

At a right angle to the grooving-jaws I arrange a pair ofvertically-disposed shapingjaws a a, which are provided with hubs andare pivoted in sliding bearings o l), mounted upon movable wedge-shapedways c c and provided with link connections d to a swinging lever e,pivoted to the central projection J, before mentioned. A link fserves toconnect the shaping-jaw and the operating-lever, as will be apparentfrom an inspection of the drawings. The swinging levers e are pivotedslightly in advance of the levers K, which fact necessitates theshortening of the links f and d and the lengthening of the links g withthe radial arms h of the sliding rod F. The levers e are also providedwith pin connections t' to engage the orificesg in a manner to operatethe wedge-shaped slides when in the extreme forward and backwardpositions, as will be obvious. The foregoing construction, as will beapparent, is substantially a duplicate of that previously described andby means of which the grooving-jaws are manipulated, the principaldifference being in the shortness of the connections, which variation isunimportant and is simply done to secure a strong pi vot for thevertical levers. The faces of the operating-jaws (see Fig. 6) arematerially different, however, one being adapted to form the groovedsides of the spike, while the other forms the fiat sides com plete,including the corners thereof.

Referring to Figs. 2 and G, it will be seen that the connecting-faces ofthe operatingjaws are specially constructed to snugly fit against eachother in a manner to prevent the accidental formation of a fin upon thesides of the spike. Said object Vis accomplished by forming two squareflanges a upon the face of top and bottom jaws, which are of a properdistance apart to form therein the smooth sides of the spike, includingthe corners of the same. The grooving-jaws are provided with centralribs O, which are of a width and depth to lit between and project upontho inside of the flanges a' of the top and bottom jaws.

The operation of my invention is as follows: A spike-blank is placedinto the machine between the jaws when the parts are in the positionshown in Fig. 4, whereupon by an inward movement of the slide-rod Fwithin its bearings G G (shown in Fig. l) and its connections, includingthe ways Q and c, the operating-jaws are rocked forward and closedinward upon the sides of the blank, after which reverse movement isimparted, which rocks the jaws backward and rolls the face of the ribsthereof into two sides of the spikeblank, thus forming grooves in twosides thereof, as shown in Figs. 7, 8, and 9. With the completion of theabove operation the ways are moved slightly down the incline, whichseparates the jaws in a manner to release the spike, which is removedand a second inserted, when the operation is repeated. During theoperation the spike-blank is stationary, and in acting upon it the jawsclose by a lateral movement, rock on their axes, and also movelongitudinally along the blank, and the construction whereby this iseifected is a novel and particular feature of my invention. This novelconstruction, which permits the blank to be stationary while the jawsclose upon it, rock, and move longitudinally without moving the blankbodily in the direction of its axes, is particularly useful in themanufactures to which it applies, and these features make it applicableto turretmachines, in which to avoid other complications the blank isnecessarily stationary durm IOC IIO

ing the time when each one of the series of forming operations is beingexecuted upon it.

Aturret spike-machine of the class referred to is shown and described inmy prior patent, No. 600,052, dated March 1, 1898.
